To all who/11, 71!; may concern.-

Be it known that l, Hnnnnivi. t5. BLYN'r, a citizen of the Unlted States,resid1ng at Steubenville, in the county of Jefferson and State of Ohio, have invented certain new and use ful Improvements in Grease Compression Cups; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to a new and novel improvement in grease-compression cups employing a gravity-weight to force the contents of the cup into the parts of the engine to be lubricated. This character of grease-cup is especially adaptable and useful on the c0nmeeting-rod of an engine or any other part where the vibration or jar is reatest, as by its peculiar construction the contents of the cup will be prevented from spilling out and the gravity-weight be kept in close contact with the body of grease contained in the cup, thus insuring an even feed of the lubricant.

in the accompanying drawings, forming a part of this specification, l: have illustrated my invention by two views, in which----- Figure 1 is a vertical sectional view of my grease-cup. Fig. 2 is a cross-sectional view of the same, taken on line 2 2 0]? Fig. 1.

Numerals of reference designate like parts throughout the dili'erent views, the numeral 1 being the reservoir or grease-receptacle portion of my improved cup, in which is operatively seated the gravity-weight 2, having a neck portion 3 and a cored-out lower portion 4:, in which is seated a Hat triction-spring 5, secured to the lower end of the stem 6, the

ends oi? said spring engaging the inside wall of the reservoir. This stem extends down through the neck and body portion of the weight 2, the upper end being threaded and joined with a securing-nut 7. A screw-plug 8 is inserted through the lower end of the weight 2 for the purpose of ai'l ording easy access to the screw securing the frictionspring 5.

Secured to the body portion of the gravityweight 2 are a pair of spring-engaging members 9 9, on the free ends of which is a hook adapted to engage with a ratchet 10, formed on the outside 01'' the reservoirportion.

cleated in a tapered cut-out portion formed. on the lower end of the gravity-weight 2 is a split ring 11, having a friction-rim 12 formed thereon, the latter being adapted to engage against the inside wall of the reservoir.

13 is a 1. acking-ring seated around the lower cndoi the weight 2. Q

lVhen the cup is in operation, the compression-weight will be resting on the grease, and with the vibration produced by the working of the engine it will cause the weight to creep downward and compress the grease more lirml y, giving it an even and regular feed whilethere is anythinglett in the cup. Should there be any sudden jolt, such as might have a tendency to throw out the weight, then the split ring 11 and the ends of the spring 5, which have been pushed upward out of the way during the period ol (JOH'iPi'GSSiOH, combincd with the spring ll'lOll'lbOl'S 9 9, will arrest the upward movement 01. the said weight as follows: The split ring 11 will be forced up on the tapered cut-out portion of the weight and by expanding the friction-rim .12 will grip against the wall of the reservoir. At the same time the spring 5 will straighten out and the ends thereof engage tightly against the wall o'l the reservoir, while the hook ends of the spring-engaging members 9 9 will lock tight in the ratchet 10. The combination of these three locking elements will thus prevent said weight from being lilted away from its seat on the body of grease, no matter how severe or sudden the jar, and the process of compression be continued as soon as the shock has passed, owing to the said weight dropping down into position upon the release o'l the friction-producing members.

The amount of compression can be regu lated by the nut '7, as by having the same loose the ends of the spring 5 will curve upward and rest slightly against the wall of the reservoir, thus allowing the gravity-weight 2 to creep down inside the cup. By tightening the nut '7 the stem 6 will be drawn upward, thus straightening out the spring 5, causing the ends thereof to grip more tightly against the wall of the reservoir and arresting the downward movement of said weight.

in order to remove the weight 2 for the purpose of refilling or cleaning the reservoir,

unscrew the nut 7 and take hold of the knob portion form ed on the neck 3. Then by pressing down on the stem 6 it will force the springointo the square recessed portion, thus throwing the ends of said spring upward clear of the wall of the reservoir. The spring-engaging members 9 9 are next lifted clear of the ratchet, in which position the Weight can be easily removed from the cup. The split ring 11 will not grip tight enough to prevent the weight frombeing lifted out.

Having thus fully shown and described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a grease-compression cup, of the character described, having-a reservoir portion in which is operatively seated a compression- Weight; a screw-regulated stem passing down through said Weight, the lower end entering a cored-out portion; and a friction-spring member secured to said stem, and seated in said cored-out portion, the ends thereof being adapted to engage the wall of the reservoir: as, and for, the purpose set forth.

2. In agrease-compression cup, of the character described, having a reservoir portion in which is operatively seated a compressionweight; a screw-regulated stem passing down through said weight, the lower end entering a cored-out portion; afriction-spring member secured to said stem, and seated in said coredout portion, the ends thereof being adapted to engage the wall of the reservoir; and a split ring, seated in a tapered cut-out portion of said weight, and having a friction-rim formed thereon adapted to engage the wall of the reservoir: as, and for, the purpose set forth.

3. In agrease-compression cup, of the character described, having a reservoir portion in which is operatively seated a compressionweight; a screw-regulated stem passing down through said weight, the lower end entering a cored-out portion; a friction-spring member secured to said stem, and seated in said coredout portion, the ends thereof being adapted to engage the wall of the reservoir; a spilt ring, seated in a tapered cut-out portion of said weight, and having a friction-rim formed thereon adapted to engage the Wall of the reservoir; and one, or more, spring-engaging members secured to the compression-Weight having on their free ends a hook-engaging portion designed to travel down a ratchet formed on the outside of the reservoir: as, and for, the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
